Not displaying on main monitor

Playing on PC and it's a major pain getting the game on the correct monitor. I have two monitors, my primary that programs initially open on and one that I use specifically for gaming. As of right now the only way for me to open the game on my second monitor is to make it my primary through display settings, open the game and adjust the resolution, then go back into display settings and reassign my other monitor to primary. Having to do this every time makes the game unplayable for me. Any help would be appreciated!
